During the preparation of a patient receiving regional anesthesia for leg surgery, what should the nurse implement to ensure safety?

Ensuring a smooth surface under the patient is crucial in the context of regional anesthesia and leg surgery. A smooth surface contributes to patient comfort and stability, reducing the risk of movement that could compromise the effectiveness of the anesthesia or the surgical procedure itself. It also helps to prevent skin injuries, particularly in patients who may have decreased sensation or movement in the areas affected by regional anesthesia.

Additionally, a smooth surface promotes better alignment and positioning, which can facilitate easier access for the surgical team and prevent complications related to pressure points. This careful attention to the physical setup can significantly enhance patient safety and outcomes during the procedure.

Considering the other options, while checking the patient's allergy history is important for overall safety, it may not specifically relate to the immediate context of positioning for regional anesthesia. Positioning the patient in a specific manner or securing limbs may be necessary, but these actions alone won't address the risk of movement or injury resulting from an unstable surface. Thus, the emphasis on a smooth surface caters directly to safety during the administration of regional anesthesia.
